Intended use

This device is intended for the following uses:

• To convey liquids and gases (including unstable measuring

media).

• To meter mass flow directly.

• To meter volumetric flow (indirectly via mass flow and

density).

• To measure the density of the measuring medium.

• To measure the temperature of the measuring medium.

The device has been designed for use exclusively within the

technical limit values indicated on the identification plate and in

the data sheets.

When using measuring media, the following points must be

observed:

• Measuring media may only be used if, based on the state

of the art or the operating experience of the user, it can

be assured that the chemical and physical properties

necessary for operational security of the materials of the

wetted parts of the temperature sensor will not be

adversely affected during the operating time.

• Media containing chloride in particular can cause

corrosion damage to stainless steels which, although not

visible externally, can damage wetted parts beyond repair

and lead to the measuring medium escaping. It is the

operator's responsibility to check the suitability of these

materials for the respective application.

• Measuring media with unknown properties or abrasive

measuring media may only be used if the operator is able

to perform regular and suitable tests to ensure the safe

condition of the device

Improper use

The following are considered to be instances of especially

improper use of the device:

• Operation as a flexible compensating adapter in piping,

for example for compensating pipe offsets, pipe

vibrations, pipe expansions, etc.

• For use as a climbing aid, for example for mounting

purposes.

• For use as a bracket for external loads, for example as a

support for piping, etc.

• Material application, for example by painting over the

housing, name plate or welding/soldering on parts.

• Material removal, for example by spot drilling the

housing.

Notes on data safety

This product is designed to be connected to and to

communicate information and data via a network interface.

It is operator’s sole responsibility to provide and continuously

ensure a secure connection between the product and your

network or any other network (as the case may be).

Operator shall establish and maintain any appropriate measures

(such as but not limited to the installation of firewalls,

application of authentication measures, encryption of data,

installation of anti-virus programs, etc.) to protect the product,

the network, its system and the interface against any kind of

security breaches, unauthorized access, interference, intrusion,

leakage and / or theft of data or information.

ABB Automation Products GmbH and its affiliates are not liable

for damages and / or losses related to such security breaches,

any unauthorized access, interference, intrusion, leakage and /

or theft of data or information.

Warranty provisions

Using the device in a manner that does not fall within the scope

of its intended use, disregarding this manual, using

underqualified personnel, or making unauthorized alterations

releases the manufacturer from liability for any resulting

damage. This renders the manufacturer's warranty null and void.

Special connection conditions

Note

The AS plug-in card (24 V DC loop power supply) may only be

used to power the internal inputs and outputs on the device.

It must not be used to power external circuits!

Note

If the protective earth (PE) is connected in the flowmeter's

terminal box, you must ensure that no dangerous potential

difference can arise between the protective earth (PE) and the

potential equalization (PA) in areas with explosion risk.

Note

• For devices with a power supply of 11 to 30 V DC, on-site

external overvoltage protection must be provided.

• You must make sure that the overvoltage is limited to

140 % (= 42 V DC) of the maximum operating voltage.

The output circuits are designed so that they can be connected

to both intrinsically-safe and non-intrinsically-safe circuits.

• Combining intrinsically safe and non-intrinsically safe circuits

is not permitted.

• On intrinsically safe circuits, potential equalization should be

established along the entire length of the cable used for the

signal outputs.

• The rated voltage of the non-intrinsically safe circuits is

U

M

= 30 V.

• Intrinsic safety is preserved If the rated voltage U

M

= 30 V is

not up-scaled when connections are established to non-

intrinsically safe external circuits.

• The information in Changing the type of protection on

page 24 must be observed when changing the type of

protection.

Devices connected to the relevant equipment must not be

operated at over 250 V

rms

AC or 250 V DC to ground.

Installation in accordance with ATEX or IECEx must comply with

the applicable national and international standards and

directives.

Installation in the USA or Canada must comply with ANSI / ISA

RP 12.6, ‘Installation of intrinsically safe systems for hazardous

(classified) locations’, the ‘National Electrical Code (ANSI / NFPA

70), sections 504, 505’ and the ‘Canadian electrical code (C22.1-

02)’.

Apparatus connected to the flowmeter must have appropriate

explosion protection approval in accordance with the Entity

concept.

The apparatus must have intrinsically safe circuits.

The apparatus must be installed and connected in accordance

with the relevant manufacturer documentation.

The electrical specifications in Electrical data on page 16 must

be observed.

Installation instructions

ATEX / IECEx

The installation, commissioning, maintenance and repair of

devices in potentially explosive atmospheres must only be

carried out by appropriately trained personnel. Works may be

carried out only by persons, whose training has included

instructions on different types of protection and installation

techniques, concerned rules and regulations as well as general

principles of zoning.

The person must possess the appropriate competences for the

type of work to be conducted.

The safety instructions for electrical apparatus in potentially

explosive areas must be in accordance with Directive

2014/34/EU (ATEX) and IEC 60079-14 (Installation of electrical

equipment in potentially explosive areas).

Comply with the applicable regulations for the protection of

employees to ensure safe operation.

cFMus

The installation, commissioning, maintenance and repair of

devices in areas with explosion hazard must only be carried out

by appropriately trained personnel.

The operator must strictly observe the applicable national

regulations with regard to installation, function tests, repairs,

and maintenance of electrical devices. (e. g. NEC, CEC).

Use in areas exposed to combustible dust

When using the device in areas exposed to combustible dusts

(dust ignition), the following points must be observed:

• The maximum surface temperature of the device may not

up-scale 85 °C (185 °F).

• The process temperature of the attached piping may up-

scale 85 °C (185 °F).

• Approved dust-proof cable glands must be used when

operating in Zone 21, 22 or in Class II, Class III.

Opening and closing the housing

DANGER

Danger of explosion if the device is operated with the

transmitter housing or terminal box open!

While using the device in potentially explosive atmospheres

before opening the transmitter housing or the terminal box,

note the following points:

• A valid fire permit must be present.

• Make sure that no flammable or hazardous atmospheres

are present.

WARNING

Risk of injury due to live parts!

When the housing is open, contact protection is not provided

and EMC protection is limited.

• Before opening the housing, switch off the power supply.

See also Opening and closing the housing on page 38.

Only original spare parts must be used to seal the housing.
